Sand Dollars
Abstract
The beach is a main catalyst in attracting individuals to cities and towns along the United States’ shoreline. It is a very valuable natural resource that is diminishing gradually. I provide background information regarding the process of both beach erosion and beach replenishment. Then I analyze two cities that underwent beach nourishment, Miami Beach and Bradley Beach, by comparing the financial aspects of the projects for these Florida and New Jersey beaches. This includes amount of sand needed, area covered, cost of project, and methods of finance. Since Miami Beach completed the nourishment project in the 1980s, there is data regarding the benefits already realized from the project. Payback from Miami Beach is compared to the minimal Bradley Beach data after only one season of replenishment. After the numerical data is laid out, the intangible costs and benefits for Bradley Beach and Miami Beach are described. The paper then moves to a data analysis section, including the cost-benefit analysis. My studytakes into account the two types of costs and benefits, and also discusses the errors in the U.S. Army Corps of Engineers’ methods of cost-benefit analysis. Due to its recent completion and lack of data, I am forced to make predictions in the final section about the future of BradleyBeach’s economic development from beach replenishment. Using similarities and differencesbetween Bradley Beach and the Miami Beach area, I ultimately suggest that Bradley Beach should not have elected to use beach replenishment to control its sand erosion.

Thirty-five percent was paid by the state, leaving the Harvey Cedars to pay only 1 percent. With this being noted, John also described some of the major terms and conditions. An easement form had to be signed by the beachfront owners. The beach also had to be accessible to the public. Most importantly, the beach must conform to federal guidelines governing water quality, beach grooming and placement of Porta Potties. John also mentioned an example where legal actions against the government, by the residents like the “Karan’s” were taken. This family had a beachline property worth $1.9 million dollars. This same property’s value dropped to $500,000 post construction of the beach with the dunes, blocking the beach view. John described the real estate subject relating to properties and the difference in price based on beach
The face of the American landscape has undergone a period of fantastic change in recent decades. With an expanding population and innumerable opportunities for economic and physical growth, urban centers and sprawling suburbs have pushed farther and farther into outlying areas causing pressures and development on previously untouched, natural lands. New Jersey has become, in many ways, the focus in dealing with issues of sprawl and development within its relatively small space. The most densely populated state in the nation, New Jersey often acts as a predecessor in both having and dealing with issues of environmental concern and/or damage. Within the past ten years, the issue of urban/suburban "sprawl" has become an issue of much concern among professional and private citizens alike. Characterized by unplanned and unchecked growth outward from urban core areas, sprawl becomes such a concern as it has reshaped the face of the American environmental landscape by fragmenting wild habitats, overutilizing existing water resources, and building mile after mile of "McMansion" homes on very large tracts of land. The construction of this suburban landscape does not, however, come without a cost to the surrounding environment. To build homes with large areas of fenced in property, open space and natural areas must be tapped utilized to feed the strong market. While some would say that it is not the market fueling the various associations of homebuilders but instead the reverse reaction, neither this, nor the other is of significant concern when attempting to address the physical impacts that this sprawling "suburban-side" has on natural habitats.
There is an important crisis in the Indian River Lagoon that nobody really wants to address. Why? Well, if everyone knew that the lagoon was so polluted, nobody would swim in it. In fact, the five counties bordering the 156 miles of the lagoon could suffer extreme economic loss. If tourists don’t come to visit the area, then the beach-side shops will certainly decrease in number, leaving more people without a job. Have you ever been outside during season (mainly early January through late March)? The snowbirds (people that come down to Florida to wait out the winter) are all over the place. They make up for a large amount of the purchases during that time. If these people think the lagoon is polluted, they might decide to go somewhere else
Semaphore Beach is affected by many factors such as natural processes and human impacts including marine litter and the discharge of stormwater. Therefore, several plans have been employed to ensure that the coast is supported through the method of counteracting erosion. However in the future, many management strategies have been put into consideration as well as the environmental, economic and social impacts as well as the predicted consequences. These impacts include traffic related incidents, noises and air pollution and the disruption of wildlife and the erosion of dunes. A method that should be considered for future management of the beach is the use of a concave sea wall, although efficient, this structure would be quite costly. Without the use of coastal management, Semaphore Beach would be unsupported, therefore negatively being affected by a variety of

Global and local sea-level has varied dramatically throughout the Earths history and are principally controlled by glacio-eustasy, thermal expansion and tectonic activity. Oxygen isotope records have help establish sea-level changes in recent geological history and it is now known that the sea-level in the British Isles has been rising for the last 18,000 years creating the beaches and coastline we see today. Present day sea-level rise is being exacerbated by anthropological causes, which is of concern due to the many millions who live by the coast. Predicting the effects of geomorphological effects of sea-level transgression is difficult, although Bruuns rule on sea-level change offer some, albeit, limited insight into predicting the geomorphological changes in the coastline.

At Site A which is the beach walk, the bipolar evaluation on coastal defences scored 5. I infer that the coastal management strategies found at Site A which are the sea wall and rip-rap are effective in preventing coastal erosion. From the bipolar environment assessment which scored 12, I infer that the surroundings are safe and clean. Additionally, the wave count at Site A was 19 waves/minute and a wind speed of 2.8m/s. This coast has high-energy waves because coasts that have high-energy waves have a wave count of more than 15 waves/minute, High-energy waves tend to erode the coast more.

People from all over the world go to beautiful beaches that are filled with water as clear as ice or as beautiful as diamonds. But, what will happen if we do not conserve the appealing sites that draw attraction to the public? Contaminated beaches has become a controversial issue to the public because of the causal problem, the harm to the people and marine animals, the government agencies supporting or opposing pollution, and the industries involved in creating such unlawful decisions. To create and find a solution, we must first find the core to the problem.
